Green House Monitoring System

Greenhouse environment, used to grow plants under controlled climatic conditions for
efficient production, forms an important part of the agriculture and horticulture sectors.
Appropriate environmental conditions are necessary for optimum plant growth, improved
crop yields, and efficient use of water and other resources.

Automating the data acquisition process of the soil conditions and various climatic parameters that govern plant growth allows information to be collected with less labor requirements. existing EMSs are bulky,
very costly, difficult to maintain and less appreciated by the technologically less skilled
work-force.In my present work again I have taken up to design this project using world’s
most powerful microcontroller Intel 8051. where I am going to analysis and use the
temperature, humidity, soil moisture and illumination.conditions.

whose moisture content is under test. The conductivity of soil depends upon the amount of
moisture present in it. It increases with increase in the water content of the soil that forms a
conductive path between two sensor probes leading to a close path to allow current flowing
through and will trigger an alarm and stop the pumps from continuously watering the plants.

Green House Monitoring Concept

Light Sensor
The light sensor is extremely sensitive in visible light range. With the light sensor attached to
the system will trigger the artificial lights automatically, when the surrounding natural lights
are low.

Artificial Growing Lights
Growing lights enable cultivators to extend daylight hours – useful for winter and spring
growing when levels of natural lights are low, and therefore can improve plants growth.
These lights will be turned on when there is no presence of lights.

Humidity Sensor
Humidity sensor is used for sensing the vapors in the air. The change in RH (Relative
Humidity) of the surroundings would trigger the Controller to activate the sprayers
Temperature Sensor It is a simple thermister circuit sensor that can be used to measure the temperature in the greenhouse. If the temperature may rises, it would triggers the cooling devices.


Sprayer produce tiny water droplets that evaporates, thereby cooling and humidifying the
greenhouse air. A misting system can provide needed moisture to maintain a healthy
humidity level of 50 to 70%.

Cooling Equipment

Vents system are hinged or track connected panels on the roof or sides of the greenhouses.
They open up the greenhouse to outside natural air. Hot air that traps in the greenhouse can
escape and allows the fresh air to enter the house. The Controller can be used to automate the
opening and closing of these vents. During the hot summer day, the bright sun may cause the
temperature inside greenhouse to an extreme heat. A cooler can be used to cool down the
environment in the greenhouse
